RAIL-JOINT.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed December 15, 1906. Serial No. 348,020.

To all whom it may concern:

Be it known that I, HENRY L. BOTKIN, a citizen of the United States of America, residing at Pawhuska, in the county of Osage and Territory of Oklahoma, have invented new and useful Improvements in Rail-J oints,

of which the following is a specification.

This invention relates to rail joints, and one of the principal objects of the same is to provide a splice bar of a single piece for connecting the meeting ends of railway rails without requiring bolts.

Another object of my invention is to provide simple and eflicient means for firmly connecting the meeting ends of railway rails which will not requirebolt holes or bolts for connecting the parts.

These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a pair of rails united by my splice bar. Fig. 2 is a plan view of the same with the rails separated from the splice bar. Fig. 3 is a side elevation of the splice bar and the two rail ends separated. Fig. 4 is a sectional view on the line 44, Fig. 1.

Referring'to the drawing for a more particular de scription of my invention, the numerals 1 designate the meeting ends of a pair of railway rails having the web portions thereof cut away for a short distance back of the ends thereof to form a recess, as shown at 3, in Fig. 3. The splice bar for uniting the meeting ends of these rails consists of a single piece or casting having a concave upper surface 4 which fits up underneath the heads of the rails, while the lower surface 5 of said splice bar is longitudinally grooved to conform to the upper surface of the base flange 6 of the rail, as shown in Fig. 4. A central recess 7 is formed in each end of the splice bar to receive the web portion 8 of the rails. 3 5

Upon reference to Fig. 4 of the drawing, it will be seen that the body portions of the splice bar at the sides thereof extend from the lower corner of the head of the rail, as at 9, in a curved line to the outer upper surface of the flange 6, as at 10, thus providing a considerable body of metal to prevent the spreading or creeping of the rails.

From the foregoing it will be obvious that a rail joint made in accordance with my invention, will not require bolts, will firmly hold the meeting ends of the rails together, can be quickly applied to the rails, while the splice bar is formed of a single piece of metal, which fits the sides of the web of the rail, and underneath the head'and over the top of the base flange so that the joint of the rail will be even and firmly held together.

Having thus described the invention, what I claim is:

The herein described rail joint comprising rails, the meeting ends of which have the web portions thereof removed for a distance back of the ends of the rails, and a splice bar provided with end recesses to fit the side of the webs of the rails beyond the cut away portions, said splice bar having a concaved upper surface to fit under the head of the rails, and a concaved-surface at the bottom to fit the upper surface of the base flange of said rails, the sides of said splice bar being curved, essentially as described.

In testimony whereof, I afiix my signature in presence of two witnesses.

HENRY L. BOTKIN.
